FYI its a 5,000 BTU unit.
So I guess I should use more gas an run it with ECO off.
Most 5000 BTU window a/c units are rated at ~5 amps. I believe your Champion is rated at ~1600 watts/~13 amps. Either this generator has very little headroom or that little a/c unit has one huge amount of inrush current when that compressor kicks on.
FWIW, the overload LED always flashes momentarily on my 3100/2800 Champion 75531i inverter generator when my Dometic 13,500 BTU a/c compressor kicks on. It flashes with the economy mode both on or off. But, to this generator's credit it still runs the a/c even if the converter is on with a discharged battery (total load approx. 20-22 amps; a/c 14-15 amps plus converter charge load of 6-7 amps).
